Step 9.
Attach the flex to the retro connector. Use three sheet metal
screws to attach the flex liner to the connector (
Figure
5.29). Mount the retro connector to the masonry wall using
masonry bolts. Redrill larger holes on connector as needed.
Be careful to ensure that the connector is centered in the
opening and the mounting holes line up with the masonry
wall.

Step 10.
Slide wall thimble cover over retro connector and secure
with masonry bolts (
Figure 5.30). If you have a framed wall
in front of the masonry, use wood screws to mount wall
thimble cover to framed wall, over retro connector and 10
in. (254mm) square framed opening (
Figure 5.25, page
20). If needed, add a section of direct vent pipe to the retro
connector in order to extend through the opening in the wall
thimble cover.
Step 8.
Secure the top adapter to the flashing. Use three sheet
metal screws through the side of the top adapter into the
flange on the flashing (
Figure 5.28). Twist lock the high
wind termination cap on to the top adapter.

Step 11.
The connection between the appliance and the retro
connector may be completed with sections of direct vent
pipe.
Step 7.
If additional lengths of flex liner are needed to span the
chimney height, use a flex coupler to connect the pieces of
flex liner together. Connect the flex to the coupler by using
four sheet metal screws for each side (
Figure 5.27).
Fire Risk.
Explosion Risk.
• Do not let the fl ex liner sag below the level at
which it will connect to the appliance or connector.
This could allow hot gas to become trapped and
potentially become a fi re hazard. The fl ex liner path
should always be sloped up toward the termination
cap.
